Can any body help me? my car is not boosting over 0.5.
Could this be the ecu? I have 93 wrx import.
I'm having a apexi power fc fitted and mapped this month.
Will this help the problem?

Thanks Charlie.

 

May be in limp mode. Try a ECU reset and see what you get.

Cheers Red.

 

i had the same problem on my MY99 mate, posted on here with no joy, tried cleaning the boost control valve with no joy and it turned out to be the air flow sensor which cost £62 from the main dealer, not sure if this helps you mate.
